Fillable Text Fields Editable AcroForm input box Static vector glyphs Preserves entered text permanently
Checkboxes & Radios Toggleable boolean fields Fixed graphic mark / tick Eliminates rendering inconsistencies
Digital Signatures Interactive signature widget Rendered image / vector line Prevents missing signature in print
Comments & Annotations Floating annotation layer Merged into page background Viewable on mobile & web readers

Frequently Asked Questions

Why should I flatten a PDF file?

Flattening locks all interactive elements—including fillable text fields, checkboxes, radio buttons, and digital annotations—into the permanent visual page stream so they cannot be edited, altered, or lost when opened in legacy PDF readers.

Does flattening reduce the file size of a PDF?

Yes, in many cases flattening reduces PDF file size by stripping out interactive Acrobat Forms (AcroForms) scripts, dynamic XFA dictionaries, and annotation metadata.

Are my confidential legal or financial forms uploaded to any server?

No. The entire PDF flattening process runs directly inside your web browser using client-side WebAssembly and JavaScript. No files or form data are ever transmitted.
